The Sterling Hill Mining Museum in New Jersey, United States, is known for its variety of immersive and educational exhibits, but is best known for its massive collection of fluorescent minerals.

The fluorescent exhibits are displayed along the walls of the so-called Rainbow tunnel that was excavated in 1990. The walls of the tunnel are lined with rare minerals that glow bright green and red under ultraviolet light.

The museum was originally an old zinc mine, and one of the oldest in the country, having opened in 1739. When the mine closed in 1986, it was purchased by Richard and Robert Hauck and opened as a museum in 1990.
